Referring to the drawings, my invention may be described as follows: I

I provide astand I having supports 2, 3, 4 and 5, angular base braces B, 6 between supports 2 and 5 and 3 and 4, respectively, andintermediate angular braces 1,! between supports 2 and 3 and 4 and 5, respectively, and table or top portion 8, all suitably secured. Onsupports 2 and 3 near their lower extremities is mounted horizontally disposed rod 9 Pivoted upon rod 9 slightly to the left of its middle portion is lever I0 having outwardly. extendingtreadle portion II and inwardly extending portion I2 with cam surface I 2a. Slidably mounted in table 8. is vertically extending rod I3 having mounted on the upper end thereof a horizontally disposed fiat plate I 4 adapted to clamp a fiat surface of work, as shown, a box cover Mai, to be operated on, against the underside of horizontal platform I5, which is supported above table 8 by means of posts I6 secured thereto. Near the lower end of rod I3 is provided a fixed, horizontal pivot pin IT to which is pivoted one endof upper link I8 of toggle I8, I9, the lowerlink I9 of which is pivoted at its lower end to pin 20 mounted on base brace 6, said links I8 and I9 being pivoted at 2I' by a pin having a horizontal extension 22.

I 8, I9 and pin 22, are so arranged and proportioned that when they are in normal position as shown in Figs. 2 and 3, if treadle I I be depressed a suitable distance, surface I2a will engage pin 22 and, through the operation of the toggle I 8, I9, cause rod I3 to rise and the plate or clamp I4 disposed on the upper end thereof approximately to engage the underside of platform I5, sufficient space being left therebetween merely to accommodate the article I la to be operated on and which is to be clamped in position as shown in Fig. 13. A stop ZIw is provided to retain the links I8, I9 in straightened position until broken as hereinafter described.

Lever 23 having outwardly extending portion 23a and inwardly extending portion 23h, suitably curved as shown in Fig. 3, is also pivotally mounted on rod 9 and so positioned and ar ranged with respect to lever I6 and treadle II that when lever 23 is in normal position, as

shown in Fig. 3, the treadle l I has been depressed to the position shown in Fig. 13 and the article to be operated on or work I4a is in clamped position as there shown, treadle II will engage the portion 23a and further downward movement of treadle IIYwill cause the outer end of lever 23 to move downward and the inner end 24 thereof to rise. Rivotally connected at one end with the .innerfri'd 24 of lever 23 is link 25,..the opposite 'end'of which is pivotally connected at 26 with vertically extending hollow rod .21.

Rod 21 at its lower end is slidably mounted upon the upper end. of vertical rod 21a whose Lever I0, shifting portion I2 thereof, rod [3, links as to engage twine or other suitable tie material 34 supplied from means positioned preferably at one side of the machine as shown in Fig. 2 and extending through guide or holding means 35, 35a, 35b and slots 3% transversely of the machine, the end 34a (Fig. 6) thereof being held by the operator at 350, so that the material will be carried through the work by the needles 30.

Cutting means in the form of a knife 36 for cutting the tie material 34 and mechanism. for operating the same are shown in Figs. 2, 3, 4, 6, 11, 12, 13, 14 and 15. Knife 36 is so constructed positioned and arranged that it will sever tie material 34 when needles 30 attain their uppermost position as shown in Figs. 6 and 14. To accomplish this rod 21 carries bracket 31, suitably secured and spaced below cylinder 29,

' bracket 31 having at one side lug or pin 38 needles or punch members 36 adapted upon up- (I ward movement of the rod 21 to pass through cut-out portion 3I of clamp I4 and suitably placed openings 32, 32 in platform I5, respectively, penetrating the work, I40, so as to make suitable holes I4a therein forthe reception of a tie 34d; an opening 8a being providedin table 8 for the passage of cylinder 29. The lever 23, the link 25, the rod 21, the: cylinder 29, and the needles 30 are so proportioned and arranged that the uppermost position. of the needles is attained when the treadle II reaches its lowermost position as shown in Fig. 14. By way of safety a stop 33 is adjustably secured to rod 27 and positionedso thatwhen the desired uppenmost position'of the needles 30 is reachedthe stop 33 will engage the underside of channelled cross-member;28, thus preventing .further upward movement of rod 27 and needles 30.

with transverse slots36a whichextend spirally part way down the sides 36b of the needles as shown in'Fig. '7. These slots are positioned so adapted to engage the free end 39 of lever 46,

which is pivoted at its other end 46a to bracket 461) secured to the underside of table 8. Knife 36 and lever 40 are normally held in the respective positions shownin Figs. 3, 11, 13 and 15 by means of springs 4 I, the upperand lower ends of which are respectively connected at 40d with lever 40 p and at 42 with bracket 43 secured to cross-membe 28, knife 36 being connected with lever 46 through links 44 and 45, which are pivoted respectively at 46c and 46; the upper end of link 45 being seated in the upper rectangular portion 41 of shaft .48 which is rotatably mounted in supports 49 secured to the top of table 8, as shown in Figs. 2, 3, 4, 5, 11 and12.

slidably mounted onrectangular portion 41 of shaft 48 is stud or pedestal 56 having at its outer end ball portion 5|, which engages socket 52 mounted on the lower end of coil spring 53; spring 53 having its upper. end seated at 54a. in cross portion of inverted U-bar 54; ,bar 54 being pivoted at 55, 56 in guides 35a and 35b, respectively. Knife 36 is also pivoted at 56 to guide 350. abutting one side of U-bar 54 and is secured thereto so as to turn with it on pivot 56. Stops 51.and 58 are provided on one side of guide 35b to limit the movement of U-bar 54 and knife 36. Stops 59 and 5911 are also provided on guide 35b to limit the movement of stud 50. r

Guides 35a and 35b are slidably mounted on guide rods 35d and 35c and are positioned adjacent the sides of U-bar 54, respectively, so that the tie-cutting mechanism may be shifted as a unit to permit the cutting of ties of various lengths, spacing sleeves 35 and locking nuts 35g being provided to secure the parts together as a unit and set-Screw 56a serves to hold the unit in selected position. Guide sac is similarly slidably supported on rods I63 mounted in supports I04 secured to table 8, and held in position of adjustment by set-screw I65; 7

Pivoted at'6ll in bracket 43 is lever 6| having outer end or handle 6Ia positioned conveniently for shifting by the operator, and its inner end pivoted at 6 I b in slot 62a at the upper end of lever 62. Lever 62 carries at its other extremity trippingblock 63, and is also pivoted at 64to sleeve 65, whichis slidable upon rod 66, the upper and lower ends of which are anchoredat 6'! in cross member 28 and at 68 in an extensionof crossmember 2T, respectively, the lower portion of rod 66 being fitted with coil spring 69 connected to sleeve 65 is arm I6 adapted to engage the lower end of rod II which is slidable within tube 12 mounted in table 8 and cross-member 28, as

shown in Figs. 3, 13, 14 and 15. Mounted on the upper end of rod 1| is block 13, provided with openings 13a through which needles 30 may pass, andadapted to ride on the upper end of cylinder 29 as shown in Fig. 14. Rectangular rubber block, or cushion piece, 14 having openings 14a therein adapted to receive needles30, engages or may be secured to the top of block 13.

Adhesive, preferably in the form of gummed tape 15, is supplied from a roll supported at one side of the stand I as shown at 15a in Fig. 2. This tape with gummed surface uppermost is run through a guide "I6 (supported at 16a and 16b) and feeder members 11, 18, transversely of the table 8 to the'inner end of guide 16 as shown in Figs. 1, 2, 4, and 8.

Pivotally mounted at 19a in a support 19 bracketed atop table 8 is a knife 80, normally held in closed position by a cable or wire 82 secured to its outer end 80a as shown in Fig. 10, and extending across the inner end of guide 16 as shown in Figs. 1, 2, 4, 5 and 8.

The other end of wire 82 is looped about arm 83 which is secured to the rod 21 as shown in Fig. 2. Also connected with rod 21 is the lower end of wire 84, the upper end of which connects through spring 85 with wire 86 which passes over roller guide 81 and is attached at its upper end 86a to the inner end of feeder member 18, which is also connected by spring 88 to guide support 16a at 89.

Feeder member 11 is provided with two downwardly extending cars 1101. which pivotally engage upwardly extending, corresponding ears 18a on lower feeder member 18. Members 11 and and associated parts are so constructed and arranged that when in normal position, shown in Fig. 2, tape being gripped by members 11, 18, cable or wire 86 is slackened by upward movement of rod 21, member 18 will be acted upon by spring 98, tape 15 released, and members 11, 18 pulled to the right to the position shown in Fig. 6. When rod 21 is retracted, cable 86 becomes taut, members 11, 18 'grip tape 15 and are drawn with it to the position shown in Fig. 5, the end of tape 15 extending a suitable distance beyond the position of knife 80 and across block 14 beneath guide I02.

Knife 80 is fitted with a spring 8i shown in Fig. 10, arranged to exert an upward pull on said knife against the downward pull of cable or wire 82. Wires 82, 84, 88 and springs 8|, 85 and 88 are so adjusted and arranged that when rod 21 is raised and the wires are slackened, knife 80 will be raisedto the position shown in Fig. 6 and in dotted lines in Fig. 10; and when rod 21 is retracted and the wires become taut tape 15 will be advanced before knife 80 is drawn downward to sever the end portion of tape 15. Stops 16c and 16d are provided on guide 16 to limit the movement of feeder members 11, 18.

Supported on bracket IOI secured to the upper side of table 8 is hinged frame or guide I02 for retaining the severed portion 15a of tape 15 in position on block 14. Frame I 02 is so constructed and arranged that when rod H is raised portion I02a will engage a knob or lug 13a andframe I02 will be raised to the position shown in Fig. 8,-and

when rod 1! is retracted to normal position frame I02 will return by its own weight to position shown in Fig. 5.

A conventional pneumatic spraying device is provided for moistening the upper gummed surface of tape 15 as shown in Figs. 1, 2, 3, 4, 5 and 15. This comprises nozzle which is connected with container 9| which is supplied with liquid from reservoir 92 through pipe 93. The spraying of liquid is accomplished by air applied to con tainer 9| through pipe 94 from cylinder 95 by theoperation of a' plunger (not shown), whose spring-pressed stem 96 may be actuated by the operation of lever GI and associated parts consisting of arm. 91 which is secured to slotted bar 98 whose slot 98a slidably engages pins 9911 projecting from support 99, the upper and lower ends of which are bracketed to the underside of table 8 and cross-member 28, respectively. The lower portion of bar 98 has a cam surface 98b adapted to engage a corresponding cam surface llifla on arm I00 which is secured to lever 6| near its lower end, and the lower end 98c of bar 98 and the upper end I00?) of arm I00 are designed and arranged normally to abut each other, as shown in Figs. 3, l3 and 14.

The construction and arrangement of lever 6| and associated parts is such that when handle 6Ia is pressed downwardly bar 98 will rise a short distance and until its lower end 080 slips off upper end I00bof arm I00 and cam surface 98b engages cam surface I00a. As bar 98 rises plunger 96 is carried upward by arm 91 applying air to the liquid in container SI and causing the liquid to be sprayed upon the gummed surface of tape 15 extending over block 14. This downward movement of handle Bla takes up the slack provided by slot 62a. Further downward movement of handle GIa causes lever 02 to act upon sleeve 65 through pivot 64 and the sleeve to rise on rod 66 producing upward movement of rod II to the position shown in Fig. 15. This is continued until the severed tape 15 atop block 14 is pressed against the severed tie material 34d and the work Ma and the tie becomes affixed to the work. Upon release of lever 6| it and lever 62 return to normal position by gravity.

Upon completion of the tie-afiixing operation clamp I 4 and work I40. may be released by a slight upward movement of handle Bla of lever 6| which causes a downward thrust of lever 62 and tripping block 63 causing the latter to en gage pin 2I22 and break the links I8, I9 and permit rod. l3 and clamp I4 to descend; spring 69 serving normally to hold sleeve 05 in such position that tripping block 63 will normally be in the position shown in Figs. 13 and 14,.i. e.,

slightly removed from pin 2I-22.

The operation of my machine may be described as follows:

The parts being in the position shown in Figs. 1, 2 and 3, tie material 34 is drawn through the guides 35, 35a, 35b, and 350, and the free end held by the operator, tape 15 with gummed surface uppermost is drawn through the guide 16 and feeder 11, 18 to the inner end of guide 16 abutting knife 80, the operator presses downward on treadle I I until portion I2 of lever I0 engages pin 2| and links I8, I9 are straightened as shown in Fig. 13 and plate I4 clamps work I 4a, as shown a box-cover, which is momentarily held by the operator in desired. operating position.

Continued downward pressure on treadle II 1 slots 30b) As needles 30,reach their uppermost position pin 38 engages lever .40 and shifts it upward causing knife 36; to shift from the position shown in Fig. 11 to that shown in Fig. 12, and out the tie material 34 at guide 3511., as shown in Fig. 6. Momentarily holding treadle II in depressed position the operator draws the tie material through the holes Ma and then releases the treadle, rod 21, cylinder 29 and needles 30 then return by gravity to the position shown in Figs. 8 and 15. Meanwhile the upward movement of rod 21 having slackened cables 82 and 84 -86 through the action of spring 88 feeder I1, 18 has been drawn to the right and knife 80 has opened as alsoshown in Fig. 6, so that upon the retraction of rod 21 and connected parts and tautening of cable 8486 and. 82, respectively, feeder TI, 18 is shifted to the left causing a portion of tape 15 to be extended over block 14 and. under frame I02 and upon completion of that shift the knife 80 is drawn downward and severs the extended portion of the tape 15a. The operator next presses handle Bio, of lever 6| slightly downward, causing an upward movement of barBB and the spraying of liquid upon the gummed surface of the piece 15a. Further depressing the handle Bla causes upward movement of rod 1| carrying with it blocks 13, 14 and piece 15a and the pressing of the latter against the exposed portion of tie 34d and work Ma as shown in Fig. 15, producing the result shown in Figs. 16 and 1'7. Rod H and blocks 13, 14 and the work Ma are then released as above stated.

Having now described my invention, I claim:
